What happened?

Example of the problem using 2024.4.1 release: https://pyscript.com/@ntoll/zipmp/latest

Notice the settings.json uses a tgz archive to be unzipped in the browser's local FS. This results in an opaque error in the console.

What browsers are you seeing the problem on? (if applicable)

Firefox, Chrome

Works fine with Pyodide but not MicroPython.

both zip and tar.gz are tested via integration tests in polyscript: https://github.com/pyscript/polyscript/blob/main/test/zip/micropython.html

true that https://github.com/pyscript/polyscript/blob/main/test/zip/tar.gz.toml parses a file with only one file, it doesn't go beyond that, but what's the content of those zip and tar.gz, if I might ask? My gut tells me it might be an order of folders issues, where in MicroPython os.mkdir can't create subfolders directly as in mkdir -p ./any/deeper/path as I don't see any other reason for this to fail with both formats ... I was trying to get those files directly to test locally, please send me both via slack as apparently attached files in GitHub are forever and used as exploit these days 😅

edit I've found a way to download those files ... investigating

@ntoll watch out, even after my fixes for the unpacking, your code uses an await in the main execution context so you better use async attribute within your script or remove that await outside any function.
